Backlog Jumps 73% to $14.1 Billion Backlog surged 73% to $14.1 billion, with electrical revenue up 81%. The company also expanded modular capacity past 4 million square feet with $510 million in bookings and hyperscaler commitments, signaling strong future demand.
Backlog growth and capacity expansion are key indicators of future revenue and competitive positioning.
Acquisition of Hunt Electric for $206 Million Comfort Systems acquired Hunt Electric for $206 million, adding about $250 million in annual revenue. This acquisition expands the company's electrical capabilities and supports growth in data-center projects.

MasTec's record backlog and raised guidance offset by weak Q2 outlook

Record backlog and raised 2026 guidance MasTec reported a record $21.4 billion backlog, up 30% from a year ago, and raised its 2026 revenue and profit outlook to $18.2 billion and $9.30 per share. Strong demand for power grid upgrades and data center connections is driving the business.
This shows the core growth story that supports the stock.
Power Delivery segment surges on utility and data-center demand MasTec's Power Delivery segment grew 19.2%, fueled by utility and data-center demand. This segment is a key part of the company's infrastructure services and reflects the ongoing need for electrical grid upgrades and connections.
It highlights a specific business segment that is performing well and driving overall growth.
Q2 earnings miss and guidance below expectations MasTec's Q2 adjusted earnings per share of $2.22 missed by a cent, and the company's guidance came in below analyst projections. The stock fell 17.7% on the weaker outlook, and some analysts cut price targets citing execution risk and weakness in the Communications segment.
This explains the main negative force that pulled the stock down during the period.
Superior Group acquisition adds data-center exposure but integration risk MasTec completed the acquisition of The Superior Group, adding data-center electrical work. While this expands MasTec's presence in a growing market, it also brings integration risk, and the bull case now depends on converting backlog and consistent execution.
It shows a strategic move that has both positive and negative implications for the stock.

The 18-month backlog hit a record $21.4B, up nearly $5B year-over-year, driven by data centers, power generation, and digital connectivity.

This is the core positive driver: record backlog and raised guidance directly boost investor confidence and future earnings visibility.

Backlog rose to $6.35B from $5.06B a year earlier, as utilities increase spending on transmission, grid hardening, and reliability amid rising power demand and data center development.

MasTec's record backlog and data-center demand offset weak guidance

Q2 earnings miss and soft guidance MasTec's Q2 revenue beat but adjusted EPS of $2.22 missed by a cent, and full-year guidance midpoint of $9.30 came in below analyst projections. The stock fell 17.7% as investors focused on the weaker outlook rather than the sales growth.
This is the main negative force this period, explaining the sharp sell-off and near-term pressure on MTZ shares.
Record $21.4B backlog boosts visibility MasTec ended Q2 with a record $21.4 billion backlog, up 30% year over year, with strong growth in Power Delivery, Clean Energy, and Pipeline. This large pipeline of future work gives investors confidence in long-term revenue and supports the stock.
It shows the underlying demand strength that counters the weak guidance and is a key reason analysts remain positive.
Analyst fair value raised on Superior Group deal A fair value estimate rose from about $349 to $427 after updated guidance and the Superior Group acquisition, which adds power delivery and data-center exposure. Several analysts raised targets, though some cut targets on execution risk and Communications weakness.
It reflects the market's reassessment of MTZ's value after the acquisition and guidance, a major driver of price direction.
Data-center and industrial demand tailwinds Citi sees accelerating U.S. industrial growth and strong data-center investment, naming MasTec as a long-term opportunity. This macro trend boosts demand for MasTec's infrastructure services, supporting future revenue and profits.
It highlights the broader demand environment that underpins MasTec's growth story and investor optimism.

MasTec raises outlook, buys Superior to expand data center work

Record backlog and raised 2026 guidance MasTec raised its 2026 revenue and profit outlook after reporting a record $20.3 billion backlog, up 28% from a year ago. Strong demand for power grid upgrades and data center connections is driving the business, which supports a higher stock price.
This is the core fundamental driver behind the stock's move and the basis for the bullish outlook.
Acquisition of The Superior Group for $1.65 billion MasTec agreed to buy electrical contractor The Superior Group for about $1.65 billion in cash and stock. The deal adds data center electrical work and is expected to immediately boost revenue, profit, and cash flow, pushing the stock up.
This is a major new event that expands MasTec's data center capabilities and is expected to be immediately accretive.
Analyst reaffirms Buy and highlights AI infrastructure demand Baird reaffirmed a Buy rating with a $473 price target, and Zacks named MasTec a top heavy construction pick, citing AI and data center investments. These endorsements boost investor confidence and can lift the stock.
Analyst and industry recognition reinforce the positive demand narrative and influence investor sentiment.
Premium valuation and mixed peer results MasTec trades at a high forward P/E of 35.6, above peers, reflecting strong growth but also raising the risk of a pullback. In Q1, revenue beat estimates but guidance was the weakest among peers, and shares fell 3.5% at the time.
This provides a balanced view, noting the premium valuation and relative guidance weakness as a counterweight.
